The wear parts of the thrust wheel mainly comprise: if the hole matched with the thrust wheel shaft, the contact part of the two sides of the thrust wheel and the side frame and the excircle of the thrust wheel are assembled with the replaceable sleeve and the replaceable pads on the two sides, the sleeve and the pads can be replaced after being worn, and the service life of the thrust wheel is further prolonged.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem that current electric shovel thrust wheel is worn and torn easily, live time is short, cost of maintenance is high in the use, providing a novel assembly structure of electric shovel thrust wheel.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides an assembly structure of novel electric shovel thrust wheel, includes thrust wheel, two copper pads, a plurality of copper countersunk screw, two copper sleeves and thrust wheel axle, two copper sleeves are packed into the axle hole of thrust wheel from the both ends of thrust wheel respectively, evenly be equipped with a plurality of countersunk through hole on the circumference of copper pad, the position department that corresponds with the countersunk through hole of copper pad on the both ends face of thrust wheel is equipped with the screw thread blind hole, the copper pad is installed on the both ends face of thrust wheel through a plurality of copper countersunk screw, the thrust wheel axle is established in the copper sleeve in the thrust wheel axle hole.
Furthermore, the copper sleeve is arranged in the shaft hole of the thrust wheel in a cold-assembling mode.
Furthermore, the number of countersunk head through holes in the circumference of the copper pad is four, the number of threaded blind holes in the two end faces of the thrust wheel is four, and the number of copper countersunk head screws is four.
The utility model has the advantages that:
1. the utility model is provided with two copper sleeves, and the two copper sleeves are respectively arranged in the axle holes of the thrust wheel from the two ends of the thrust wheel, thus the assembly difficulty is smaller than that of the whole copper sleeve; the utility model discloses a copper pad is installed on the both ends face of thrust wheel through a plurality of copper countersunk screw, after thrust wheel copper pad and copper sheathing wearing and tearing, can conveniently dismantle, copper sheathing and copper sheathing are as the consume piece like this, in case wear the limit can change, and need not change the thrust wheel, and then the whole life of extension thrust wheel practices thrift a large amount of costs.
2. The utility model discloses a thrust wheel copper pad adopts the fix with screw, can not drop when assembling with the thrust wheel axle, and stability is good, has reduced installation time, has improved work efficiency.
3. The utility model discloses assemble simple, compact structure, it is firm, can increase electric shovel thrust wheel live time by a wide margin, can practice thrift a large amount of cost of maintenance simultaneously.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 to 5, the assembly structure of the novel electric shovel thrust wheel described in this embodiment includes thrust wheel 1, two copper pads 2, four copper countersunk screws 3, two copper sleeves 4 and thrust wheel shaft 5, two copper sleeves 4 are respectively installed into the shaft hole of thrust wheel 1 from two ends of thrust wheel 1, so that the assembly difficulty is small compared with that of a whole copper sleeve, and the assembly mode of copper sleeves 4 is cold-assembling and interference assembling. Evenly be equipped with four countersunk head through-holes on the circumference of copper pad 2, the position department that corresponds with the countersunk head through-hole of copper pad 2 is equipped with the screw thread blind hole on the both ends face of thrust wheel 1, copper pad 2 is installed on the both ends face of thrust wheel 1 through four copper countersunk head screws 3, and copper countersunk head screw 3 is the same with the copper pad 2 material, need not to pull down after the assembly. The thrust wheel shaft 5 is arranged in the copper sleeve 4 in the shaft hole of the thrust wheel 1.
The utility model discloses an assembly process as follows: firstly, a copper sleeve 4 is respectively arranged at two ends of a supporting wheel 1 in a cold assembly mode, 4 countersunk through holes are uniformly processed on the circumference of a copper pad 2, 4 threaded blind holes are respectively processed at two end faces of the supporting wheel 1 according to the same position, when the supporting wheel 1 is assembled with a side frame through a supporting wheel shaft 5, the copper pad 2 is firstly attached to two ends of the supporting wheel 1, then copper countersunk screws 3 are screwed into the countersunk through holes, and the copper pad 2 is fixed at two end faces of the supporting wheel 1 through the copper countersunk screws 3, so that the copper pad 2 can not fall off in the process of assembling the supporting wheel 1, the installation time is shortened, the working efficiency is improved, and meanwhile, as the copper countersunk screws 3 and the copper pad 2 are made of the same material, the copper countersunk screws 3 do not need to be detached after the assembly. Thus, the copper sleeve 4 and the copper pad 2 are used as wearing parts and can be replaced once the wear is over-limited, and the supporting wheel 1 does not need to be replaced, so that a large amount of cost can be saved.
